Be it known that I,"HANS C. HANSON, a

'- citiien of the United States, residing at Albert Lea, in the countyof Freeborn'and State of Minnesota, have invented a new and usefulImprovement in Folding Camp- Stoves, of which the following is aspecification. p This'invention relates to improvements in folding campstoves, and more particularly to that type employing a hydrocarbonburner. More particularly this invention relates to a stove which canbepacked in compact form and easily and quickly unfolded and adjustedfor use, and which when unfolded and adjusted produces a simple andeffective stove for cooking and heating purposes. I

. In the accompanying drawing forming part of this specification, Figure1 is a plan of my invention when packed fortransportation and the coveris removed; Fig. 2'is a section of a detail of the burners taken on theline X--X of Fig. 1; Fig. 3 is a section of a detail of the receptacle.looking at the side through which the handle 39 is adapted to move Fig.4 is a section of a-detail of the receptacle when its body is erected onthe cover; Fig. 5 is a section of a detail the casing, which is ofrectangular .form and resembles a receptacle of medium depth, the

vbottomf2 of which isprovided with a plurality of draft openings 3through which air is free to pass upwardlyinto the receptacle .to supplyoxygen to the flames of the burners. .Each corner of the receptacle isprovided with a movably disposed leg 4 in the form ofa vertical rodhaving afioli'set or shoulder 5 at its'upper end, said rod beingslidably engaged in a tube -6 in the corner of thereceptacle, said tubebeing secured by rivets? or other suitable means to the casing and beingprovided with a longitudinal opening 8 or passage in its side throughwhich the shoulder end of the rod may slide Application filed July 21,1917.

.slot or lateral passage 10 in the tubular member where the leg islocked in extended position and. prevented from receding upwardly. InFig. 3 the le is illustrated in folded condition while in Fig. 4 it islocked in extended position as described. The legs and their holdingmeans are all similar inconstruction, there being one provided in eachcorner of the receptacle. The upper portions of'th'e sides 11 and 12. ofthe re ceptacle are provided with-a pair of horizontal longitudinalledges 13 upon which rests a grate 14, said grate being made out of asingle rod formed into rectangular convolutions, the ends of saidconvolutions being adapted to rest on the ledges 13 as illus trated inFig. 1 from the receptacle as also are the legs, so

cleaned from time .to time. A removable -cover B is provided on thereceptacle, which,

can be securely closed thereover by means of the studs 15 on the ends 16of the receptacle, which are adapted to be sprung into engagement withthe cover through 0 en'- ings 17 in the ends 18 of the cover, (seeig.3); When the stove is in use and'the cover removed, the cover can beinverted and used asa tray to support the extended legs of thereceptacle.

Disposed within the receptacle is a burner fixture C-formed withsupports 20, which are rigidly secured to the bottom 2 of the recep--The burner fixture is in the form of a duct 22 having uptacle by rivetsor bolts 21.

turned ends 23 and 24. The ends 23 and 24 are formed with horizontalburner bases 25- This grate is separable i that the parts can beseparated and easily and 26, of burners D and E, resembling disk orcircular plates. A burner cap on base member 25 is in the form of a ringmember 27 'having radiating ribs 28 on its lower surface and radiatingribs .29 on itsupper surface forming channels through which gas from theduct 22 may pass outwardly. Secured over the ring 27 is a. burner cap29, which is formed by a plate having a shallow centrally disposed cup30, in which gasolene or other hydrocarbon liquid may be placed andignited for heating the burner'to start the generation of gas. The outerperipheral edges ofthe cap piece 29 and the base member 25 are formedwith inturned shoulders 31 which act as deflectors to direct the flow ofgas through the channels between the ribs 28 and 29 and commingle theconstituent parts of the gas to form an efi'ective gaseous fuel medium.The 'cap member 29 is secured on the ring member 27 and to the basemember 25 to hold said parts together by means of the screws 32. Theburner E on the upturned end 24 of duct 22' issimilar in construction tothe parts of the burner D just described, excepting that the cap piece33 is secured over the ring member 34 and to the base member 26 by asingle screw 35.

The supply of fuel mixture to the burner E is controlled b a valve 36,which is ada ted to seat at 37 1n the duct and is provi ed with threadedvalve stem38 having a key 39 slidably mounted thereon, said key beingjoined to the valve stem 38 by a lug and slot connection 40, whereby thekey 39 may be extended or receded through an opening 41 in the end ofthe receptacle A, sald key bein extended when it is desired to turn theva ve and open or close the same. The valve stem 38 is threaded in astopper 41. in one end ofthe duct.

Fuel mixture is admitted into the duct nection i or' stopper 44 beingprovided through which the tank can be filled and air pressure appliedby, means of the pump 45 or other suitable means. A suitable supplynozzle is secured and connected with the tank by the threaded coupling46, said 4 nozzle bein provided with a gas generating tube 47, w 'ch hasa coupling member 48 onits outer end, said coupling member being adaptedto be detachably secured in the upper end of branch member F andconnected with the duct therein to supply the hydrocarbon mixture fromthe supply tank to the burners. The point at which the coupling 48 isattached to the branch F is disposed so that the generating tube 47 willextend across and immediately above the burner D, whereby heat from theburner either supplied by the burning gases from the fuel in the cup'3Oor from the burner proper will start and continue the generation of gasin the tube before it is admitted into the duct C. The supply nozzle Hhas threaded therein the stem 49 of a valve 50,

which is seated in the coupling member 48.

The valve stem is threaded in the nozzle member H and extends outwardlytherefrom being provided with a handle 51 by which itcan be turned. Thenozzle member passes through an opening 52 in one of vent the supplytank from being unintentionally detached from the burner fixture when inuse. It will be noted that the burner cap 29 is provided with the usualperforations immediately below the gas generating tube 47, through-whichsome ofthe gas may pass to produce a heating flame below, and in contactwith the generator tube to heat the latter,

In use, assuming the stove to be folded, the cover is first removed andthe legs extended and locked in extended position and. then placed withtheir lower ends upon the inverted cover. The supply tank after beingremoved from the receptacle is inflated by pumping air into it and issecured by its generating tube to the receptacle. A small amount ofgasolene is then placed in the cups of the burners and ignited. Afterthe burners and generating tube have been heated by burning the gasolenein the cups the valve 50is opened by turning the handle 51. The gasgenerated by the generating tube is thus admitted into the duct fromwhence it asses outwardly through the burners and is ignited. Theresulting flames continue the generation of gas in the burner tube andin the duct, and as a result an emcient heater is provided for cookingand heating purposes by the burners. When desired onlyone burner need beoperated, the valve 36 being provided for cutting 0d the supply of gasto the burner E. The parts of the device can easily and quickly be setforth within the scope of the following claims.

Having described my invention, what I claim as new and desire to protectby Let-.

7. The structure set forth in claim 6, said casing having a ledge nearthe upper edge of its side portion, and a grid member adapted to besupported on said ledge below the top edge of the casing.

8. The structure set forth in claim 7, a flange cover adapted to fitover the top of the casing, and means on the casing engaging said coverto hold the same in position.

' 9. A folding camp stove having in combination a substantiallyrectangular casing having a perforated bottom, a stove having aplurality of burners fixedly secured to said bottom, said burners beingdisposed below the top of said casing, legs at each corner of saidcasing adapted to be received therein, said bottom having holes throughwhich the legs are adapted to be extended when the stove is set up foruse, means on said casing for holding said legs extended, said casinghaving a ledge at the upper inner side thereof, and a grate adapted tobe supported on said ledge. y

In testimony whereof, I have signed my name to this specification. I
